GZE supercharger onto 20v

[pornstr20v]

i guys i have a 4age 20v and i was thinking if i can put a supercharger from a cze on a 20v
what mods would you need to get it to work?

has anyone done it b4?

[too_quick]

I've been told the sc12 will run out of puff up in the revs.

plz guys i would like to know

[blacktop]

I have herd (a long time ago) of a guy in the UK doing this, it seemed to work but i have no details of the setup or anything, but at least you know it has been done before.

Try searching Google

put a trubo on a gze engine, i think your wasting your time with this supercharger idea. toyota really have never made a good supercharger. with the internals of the gze and a turbo to suit (ca18 comes to mind) you could build a cheaper, better and stronger motor

pm 30psi4agte he knows all the in and outs of these motors

i was going to put one of those sc14 superchargers on a 2.2L 18rg some time ago, just about every engine builder recommended against it, look up bluewire, it is a fantastic show car but reall no oomph to it at all. i spoke to the guy who owns it, sean i think his name was sean, he was having probs with how hot the sc ran too

heres one for ya, its been done and then some. hope it helps.http://come.to/twincharger

on a personal note. i was planning on building the whole twincharge monster. and am now beginning to have doubts. never mind cost, just the complexity of the whole thing. you can get some pretty impressive turbo's these days and save youself some hassle.

at any rate good luck!

buy this stuff, see how quick the other gear went

just use a smallport GZE, cut'n shut manifold, and replace blower with turbo

forget about the 20v idea

[AE25]

im doing so at the mo
although turbo is much better suited to the 20v im trying out the (sigh) tc setup.

going on net info.. its not the 'puff' the roots charger runs out of, but more inefficiency at higher boost levels.. the sc12 creates too much heat the higher you overdrive them, until either you start losing power due to less air density or the rotor coatings melt. 14psi (cusco pulley) seems to be the limit before heat is too much of a problem.
Removing the dog leg gze intake for an equal length runner intake would help improve flow up top end.. probly another reason gze owners say the sc12 runs out of puff

so far ive found (in rwd layout) the gze bottom charger mount needs 8mm milled off the underside of it to sit on top of ae86 engine bracket. fwd wont have this issue. move alternator to exhaust side somehow. the top of the charger interferres with the water pump inlet pipe from the head.. so something custom needed there. then new top bracket needed to be made for the charger to bolt to. the knock sensor is in the way of the charger inlet pipe so either remove it or drill/tap the boss where the 4agze knock is mounted between cyl 3 & 4. or make custom sc inlet pipe.
on a blacktop, you may have clearance issues on the hydraulic belt tensioner.. i dont have the tensioner yet so not sure on fitment.

another mod i've done is use the smallport 16v backing plate for the water pump and turned 1.5mm ish off where the impeller contacts so can still run the 20v pump. this gives me a flange at the back of the water pump to mount a steel pipe rather than the 20v's rubber hose as theres not much room to view any water leaks if it happens.
with the 16v smallport steel pipe fitted to water pump, the charger just touches it when pulled fully towards engine. the gze steel pipe is shaped a bit different and clears it.

sc bracket fitted


sc fitted but can move closer to engine once knock sensor and vacuum lines under quads removed.


20v water pump backing plate (rubber hose off the back)


sc fits right up close to the water pump when in the original position like a gze


with 16v water piped fitted with 16v backing plate.. sc intake contacts it




not much room for 20v water outlet pipe

that as far as i've got so far.

Blowoff on a supercharger setup? Does he realise that in a setup like that it's likely that manifold vacuum will be holding the blowoff open in off-boost running?
He should have a filter on that trumpet to prevent junk getting in as some of his intake charge will be coming in though that valve until he gets on boost.
Hope he's not running an AFM setup too, as the above situation will be bypassing the AFM, but if it's all sorted, looks like a nice setup indeed.

[AE25]

hmm either way it works well. it used to be 16v which it did a high 13sec 1/4 mile, and apparently its faster now

[TERRA Operative]

Looking at the setup again, I assume he would be running an aftermarket ECU?
If so, most of the problems I outlined would be moot.

Do you have pics of the bonnet? I'm interested in the intercooler setup.

[JP]

the BOV should work fine in that setup as the throttle body is after the charger, not before the charger like the stock 4agze setup.

[TERRA Operative]

Ah, true. If it is AFM though (looks like a silvertop) you'll still be venting metered air. Although if an aftermarket ECU is employed, MAP sensing would probably be in use.

Need more pics!

[AE25]

i put a link just above the last pic.. zak, the new owner put up some details and pics on toyspeed.org.nz forums. car was built by tim (tiny), at the time a garagedori team member who now living in aus.
